Degree of protection
(excluding battery
compartment)
A) The working range increases depending on how well the
laser light is reflected from the surface of the target (scattered,
not reflective) and with increased brightness of the laser point
to the ambient light intensity (interior spaces, twilight).
In unfavourable conditions (e.g. when measuring outdoors at
intense sunlight), it may be necessary to use the laser viewing
glasses.
B) +0.1 mm/m at unfavourable conditions, e.g. at intense
sunlight
C) In the continuous measurement function, the maximum
operating temperature is +40 °C.
The measuring tool can be clearly identified with the serial
number 18 on the type plate.
